This Phase I System Impact Study executive summary report has been prepared in accordance with the PJM Open Access Transmission Tariff Part VII, Subpart D, section 309. This report presents an executive summary of Phase I System Impact Study results for New Service Requests (projects) in Transition Cycle 2.

The Phase I System Impact Study is conducted on an aggregate basis within a New Services Request’s Cycle, and results are provided in both (i) a single Cycle summary format and (ii) an individual project-level basis. The Phase I System Impact Study Results (for both the summary and individual reports) will be publicly available on PJM’s website. Project Developers must obtain the results from the website.

In accordance with PJM Manual 14H, section 4.3, PJM takes the following actions during the Phase I System Impact Study:

1. PJM studies each New Service Request on a summer peak, winter peak and light load RTEP base case study. The case year is dependent on the new services cycle under study. PJM will identify the base case year to be used in the study of a specific cycle on its website.
2. PJM will only perform load flow analysis during the Phase I System Impact Study.
3. In Phase I of the Cycle, PJM conducts an Affected System screen to identify any New Service Requests with Affected System impacts and provides each Affected System Operator with a list of New Service Requests in the Cycle with potential impacts to their respective system.
4. PJM will create both the short circuit and stability base cases to be used in the Phase II System Impact Study.
5. The Phase I System Impact Study results will be publicly available on PJM’s website. Project Developers and Eligible Customers must obtain the results from the website.

PJM received 450 New Service Requests in Transition Cycle 2, Phase I with a combined Maximum Facility Output (MFO) of 45,977.6 MW and 33,857.2 MW as Capacity Interconnection Rights (CIRs). All of these New Service Requests are listed in table below.

Stability analysis is not performed as part of the Phase I System Impact Study. Stability analysis will commence in the Phase II System Impact Study.

At PJM's discretion, New Service Requests in a Cycle at the same Point of Interconnection may be aggregated for the purposes of Phase I System Impact Studies, in accordance with PJM Open Access Transmission Tariff, Part VIII, Subpart C, section 404.2.a.iii.

The following Transition Cycle 2 Phase I projects intend to claim and transfer CIRs from deactivated capacity generation resources. PJM performed a reliability analysis of the impacts to the system capability for the proposed transfers of CIRs from the deactivated generation resources.

Table below shows a summary of the total planning level cost estimates for each individual New Service Request received by PJM and studied in Transition Cycle 2 Phase I. These network upgrade costs are subject to change as a result of a facility study performed by the Interconnected Transmission Owner during the Phase II and III System Impact Studies.
